摘要
Facile access to optically active pyrroloindoles by Fischer-type pyrroloindole synthesis is investigated. The reaction using chiral hydrazines prepared from commercially available chiral amines proceeded with diastereoselective cyclization (up to 70% de), and a short-step conversion of the cycloadducts to (-)-desoxyeseroline and pyrroloindole alkaloids was achieved.
